'Casual' Tux Jacket Look

I found tux jacket at the local thrift. Really nice J Press and felt bad leaving it, BUT have no clue how to wear it out as the pants were no where to be found. 1 Button, Peak Lapel (satin), unvented. Any pictures or suggestions of how to rock this

Yes there are great deals at thrift stores on suits, a man buys or has made a new suit wears it once or twice and it ends up at the thrift store. Which leads me to this question I have a Ratner suit jacket (dark gray pinstripe) very nice, I no longer have the matching pants can this jacked be worn with other pants?
